Quick answer: Protein Drink Mix (PDM) is a vanilla protein powder with 15 g of protein per serving that you can drink on its own with water — or, as most Herbalife customers use it, stir into a Formula 1 shake to make it thicker, creamier and noticeably more filling.
What Protein Drink Mix actually does
The most common complaint about any meal-replacement shake is hunger returning too soon. Protein is the most satiating macronutrient, so adding a scoop of PDM to your Formula 1 raises the protein content of the meal and keeps you satisfied for longer — the difference between making it comfortably to lunch and raiding the biscuit tin at 10:30.
Two ways to use it
In your shake: add one scoop to your usual Formula 1 blend. The vanilla flavour pairs with every Formula 1 variety, and the texture becomes closer to a thick milkshake. On its own: mix two scoops with 250 ml of cold water for a light high-protein drink between meals — useful on training days when your protein target is higher.
Who benefits most
Anyone replacing two meals a day (the extra satiety makes the plan far easier to sustain), anyone who trains regularly, and anyone who finds a standard shake “not quite enough”. It is included in both the Complete Package and the Protein Program for exactly this reason.
Frequently asked questions
Does PDM replace Formula 1?

How much protein do I get in total?
Formula 1 with milk plus one scoop of PDM delivers roughly 24–25 g of protein per shake.
Is it suitable for vegetarians?
Yes, PDM is suitable for vegetarians.
